The lament from an old country song ,"You slip through my fingers just like quicksilver," describes the most unusual-appearing of the American skinks perfectly.



Long placed in the monotypic genus Neoseps, the Florida sand skink is now known as Plestiodon reynoldsi. This fossorial skink is highly specialized for a life of burrowing in the sugar-sand locales (often low dunes) of central Florida.

Although four limbs are present, they are tiny. The forefeet bear only a single toe each and the slightly larger rear limbs bear two toes each.



The eyes are small and the lower eyelids each have a transparent "window." Despite the very real limb-size reduction, this silvery 3-1/2 to 5 inch long lizard is alert, remarkably agile, and very difficult to hold.

Whether found by accident or as the result of a concerted effort its response to the light is immediate and decisive: it dives headfirst into the sugar-sand and within a fraction of a second has disappeared into the substrate for which it is so very well-adapted -- and named.

Along the side of the road that had traversed the driest-appearing of desert lands, a small sign proclaimed the presence of a spring.

A widened parking spot beckoned us to stop for a few moments and stretch our legs. We found the little spring, and, while limbering up from the long drive, checked the area over carefully for herps and birds to photograph.

We found little, but as it turned out, a most impressive find found us. We were standing next to a treefall when a fleeting movement among the broken limbs caught our eye. Whatever had made the motion had disappeared again and we had no idea of what the perpetrator was.

That we decided to stand quietly for a few more minutes proved a wise decision. After about five minutes we noted more motion, this about 3 feet away from the initial occurrence. And as we watched a shiny tan lizard head pushed above the twigs and a beady eye watched us intently.



We remained as motionless as possible and a minute or two later the lizard felt secure enough to emerge a little further. Following an elapse of another several minutes the lizard was finally lying fully in a patch of sun. And a rarely seen lizard it was. By accident we had happened into the habitat of the beautiful Panamint alligator Lizard, Elgaria panamintina, just as one lizard had become active for the day.

And to make the sighting even more memorable, the lizard appeared to be a gravid female! Now that's luck!

A half dozen intrepid explorers walked a narrow forest trail on Madre Selva Preserve in Amazonian Peru, each apparently stepping over a patch of leaves on the trail. They walked a few hundred yards beyond, then turned and retraced their steps.

As they neared the bit of leaf cover on the return trek, the head of a small snake was seen protruding from beneath the leaves. Carefully collecting the snake, they brought with them to the field station the only pygmy black-backed coral snake, Leptomicrurus scutiventris, we have yet seen there.

The snake was photographed and released exactly where it had been found -- note that a single ring of yellow on the head and one or two rings of orange on the tail are the normal pattern for this snake:



This species attains a length of about 18 inches but is usually smaller. Remaining is the question of whether this tiny elapine snake is actually rare or merely secretive? But for those of you who believe the red to yellow rhyme (red to yellow, kill a fellow; red to black, venom lack) infallible, take note. This is just one of the many neotropical coral snakes to which the familiar ditty does not apply.
